Outlook wont run up, mail control panel applet says I have run out of resources

Environment:
Windows 7 Professional, Outlook 2010

I have been using Outlook for a couple of hours without issue. I then rebooted my machine and went to run Outlook and received an error dialog with "Cannot Start Microsoft Outlook". I then tried to run outlook in safe mode:

outlook /safe

outlook /safe:1

outlook /safe:3

outlook /safe:4

outlook /resetnavpane

Nothing worked so I tried a repair of my Office install, followed by an uninstall of Outlook and a re-install. Still no joy.

I then attempted to open up the "Mail" control panel applet and receive a warning dialog of "Your system needs more memory or system resources. Close some windows and try again."

As this is a fresh boot and the machine has 3GB of free RAM resources is not the problem. I suspect I have a corrupt profile. Can anyone shed any light on this for me? Anything I can try? I was hoping that Outlook was going to prove more stable than in the
past with more informative error messages *sigh*.

I renamed the HKCU\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem to "Windows Messaging Subsystem OLD" (no need to do anything in HKLM in my case). Then I was able to open the "Mail" Control Panel and create a new profile. Nice
one!

You have two options: completely uninstall office and reinstall - delete all office files from the hard drive, all registry keys. Actually, since it works on the other system, deleting *all* outlook registry keys and repairing might fix it.

If you aren't in a hurry and want to try different things - delete the windows messaging subsystem key in HKCU and HKLM and repair. If that fails, delete it and all outlook keys you can find then repair.

I had a single "Internet Email" account configured. I am not running this under Terminal services. Its a native Win7 32bit (not xp mode) run of Outlook 2010. I have also checked the event viewer logs and there are no errors listed in either the application,
system or security logs.

And a complete re-install of Office still produces the same error messages described above. So I must have an issue in the registry somewhere. I have also renamed existing folder that contained my PST in case that was causing an issue (even though repair
tool reported no errors).

Other Office applications start up fine. It has to be related to profiles in some way as Control Panel > Mail won't open with the resource error above. But after a fresh reboot and over 3GB of RAM free this is not the case.

I then did Step 4 and surprisingly the key did not change and was still totally empty. Attempting step 5 I still received the error message dialog "Cannot start Microsoft Outlook." And then attempting to open Control Panel > Mail still produces the warning
dialog "Your system needs more memory or system resources. Close some windows and try again".

So basically I cannot run outlook.exe and I cannot use the control panel applet to manage my profiles.

I am nothing but a patient and desperate man :-). I removed the key in HKCU and HKLM as described. Then *before* opening Outlook I opened Control Panel > Mail and hey presto it opened with no profiles (as expected)! I did *not* open Outlook at that point.
I did a repair and a reboot. Just to make sure things were as I left them I attempted to open Control Panel > Mail and it still opened and had no profiles. Which was good. I then ran up Outlook and it had the default "Outlook" profile as the selected profile.
I decided to create a new profile and then went through the steps of creating that profile and pointing it to my original PST file. Outlook started fine and subsequent restarts also worked.
